The patch titled
Subject: mm: un-export wake_up_page functions
has been removed from the -mm tree. Its filename was
mm-un-export-wake_up_page-functions.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Nicholas Piggin <npiggin@xxxxxxxxx>
Subject: mm: un-export wake_up_page functions
These are no longer used outside mm/filemap.c, so un-export them and make
them static where possible. These were exported specifically for NFS use
in commit a4796e37c12e ("MM: export page_wakeup functions").
